Why did my boyfriend send me this?

Okay so I am literally the worlds BIGGEST IDIOT when it comes to dating I mean I know how everything works but I now have my first actual real boyfriend. I mean I have dated before but it was those stupid little kid relationships that didn't mean anything or last long at all.😂 But anyways my boyfriend sent me the heart emoji with the arrow through it "💘" what does this mean? Why did he send me this?
